Agree or no?

I've noticed that it's a bit of a hassle having to change the poster of a certain post/topic. My suggestion is that we should be able to change the post and/or topic's author, so if someone leaves the forums and has an important topic, instead of having to repost the topic yet again, a moderator or admin can switch the topic author. It doesn't have to be an important topic, but anything that would need an author switch.I'd suggest having it under the '?' part of a post, but anywhere will do.
